SPECIFICATION forming part of Letters Patent No. 343,941, dated June 15,1886.

Application filed November 7, 1885. Serial No. 182,082.

To all whom it may concern:

Be it known that I, WALTER E. BENNETT, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented new and useful Improvements in Methods of Stitching Shank-Buttons to Fabric or Leather, of which" the following is aspecification.

This invention relates to an improved method'of securing shank-buttonsto fabric or to leather by stitching, the object being to provide astitch having such a disposition of the threads forming the same,together with such a number of the latter that a stitch of greatstrength is formed either for the above-named purpose or for unitingfabrics, and the threads of which are not displaced or drawn out by anystrain that they may be subjected to, even though the thread be outbetween the several stitches.

In the drawings forming part of this specification, Figure 1 is anenlarged perspective view representing a piece of material through whichthe thread is carried to form a stitch, the shank and adjoining side ofa button, and a series of threads passing loosely through said materialand button-shank, (to more clearly illustrate their relativedisposition,) which are looped togetherthrongh said material,therebywhen drawn tightly against the opposite sides of the latter forming astitch embodying my improvements. Fig. 2 is a perspective view ofa stripof material having several buttons secured thereto by said improvedstitch, the appearance of the latter when drawn against both sides ofthe material being shown in this figure. Figs. 3 to 8 illustrate thevarious stages of the work in its progress.

In the drawings, D indicates the material or fabric in which the stitchis made. E is the button, and at its shank or eye.

In carrying out my invention the thread a, Fig. 1, leading in thedirection of the arrow near the same from the stitch last made in thematerial, is engaged by a needle of the wellknown side-cutdescription,and a primary loop is thus formed and drawn up through thema terial at 3, (see Fig. 3,) and the needleis then carried down throughthe material, and the eye (I of the button drawing with it said primaryloop 9, (see Fig. 4,) which consists of the (No specimens.)

double'd threads at a under the fabric, the end 4 of the threadrepresented in loop 6 by the part8 of the thread) being then carriedthrough said primary loop and doubled backward on itselfformingsaidloop6. (See Fig. 5.) Meanwhile the needle has been disengaged from loop 9and withdrawn from the material and again pressed through the latter at3 and engaged with the part 7 of the thread, and is again drawn upward,having the loop 10 attached to it. (See Fig. 6.) The needle is thencarried a/second time down through the material and the eye or shank dof the button 'at 5, drawing two more threads through the latter, makingfour in all, and carrying the loop 10 under the fabric, as shown, (seeFig. 7,) and then the end 4 of the thread a is carried through said loop10 and led off to form another stitch. (See Figs. 1 and 8.) It will beunderstood that in forming the stitch as aforesaid after said primaryloop is made and carried under the material and the thread 7 has beenpassed through it, the latter and said loop are drawn tightly againstthe sides of said material before the secondary loop 10 is formed, andin like manner after the latter step in the formation of the stitch theend 4 of the thread a (first having been passed through loop 10) isgiven a suitable tension to bring all of the threads composing thestitch to the positions or into the close relations with the buttonshankand fabric shown in Fig. 2. This tightening of the threads cannot beshown in the diagrams Figs. 3 t0 8.

The appearance of the finished stitches on both sides of the material isillustrated in Fig. 2 and the relative disposition of the aforesaidloops is also there shown.

It is obvious that the within-described stitch or stitches may beemployed for uniting the edges of fabric and for many kinds of stitchingother than that required for attaching buttons to materials. Said stitchis formed, asis seen, by passing the threads which form it through thematerial at only two points in attaching buttons thereto or for otherstitching, and-the threads are so interlocked with each other beneaththe fabric that no strain that can be exerted on the buttons E cancausethe th reads of the stitch to slip, though the threads be tween thelatter be cut.

. to fabrics herein described, which consists in drawing aloop of threadup through the fabric outside the eye of the button, carrying the loopthrough the eye and down through the fabric,

then passing the end of the thread through said loop below the fabricand doublingit back ward, then drawing a second loop up through thefabric close beside the first loop, and passing interlock, substantiallyas described.

said loop in like manner through the eye and down through the fabricclose beside the first r5 loop,then passing the end of the threadthrough this second =loop close to the first loop,whereby the loopsabove the fabric which pass through the eye are close together andparallel, and the loopsbelow the fabric lie close together and 20 WALTERE.
